Back when we were kids, "security" meant little more than having a secret password to keep little siblings out of the treehouse. That's still the case in some situations. Take the title of this column, for instance. If you go to the #linuxjournal IRC channel on FreeNode, saying "Lapsang Souchong" will mark you as part of the inner circle. (Note, this does not make you one of the cool kids...possibly the exact opposite!)
When it comes to computer security, however, things are quite a bit more complex. Whether you want to encrypt your data or lock down network access, Linux provides a wide variety of security tools. This month, we focus on using those tools in our Security issue.
